Hi i'm an 18 year old male my ecg shows irbbb and probably normal ecg i don't have any heart related symptoms but i have tsh of 0.013 should i worry?

ECG, TSH: IRBBB without any cardiac symptoms is common, and not specifically worrisome but can be seen in atrial septal defect, so if that were a clinical concern, an echocardiogram would be helpful. The TSH level is low and needs further evaluation. Here is a helpful article on low TSH. http://www.mdedge.com/ccjm/article/95238/endocrinology/approach-low-tsh-level-patience-virtue
